Treatment method for rotten roots of Picea macrophylla
Huperzia serrata is a desert plant, which is very drought-tolerant. If you don't water it for two months in winter, you will be fine. If you water too much or the temperature is too low, it will lead to root rot. How to take root after root rot? If Huperzia serrata root rot is found to be serious, it should be cleaned in time, dried in the shade and replanted at a temperature of 20 ~ 30℃.
If the root rot is not serious, you can cut off the rotten place first, soak it in carbendazim solution for disinfection, put on new soil for disinfection in the sun, and then reduce the number of watering. Too much watering will cause root rot to happen again, so water it normally after new roots grow.
